The Gospel is the astonishing news that something has happened to the Son of God, and the equally astonishing news that in Him something has happened to the human race. If the whole human race fell into ruin in Adam- a creature, a mere man- what happened to the human race in the death of Jesus Christ, the incarnate Son of God? Paul tells us. When Jesus Christ died, we died. But that is only the beginning. When He rose, we rose. He ascended and sits at the right hand of God the Father almighty, the place of honor and love and delight and complete and utter acceptance, and Paul tells us that in HIs ascension we too were lifted up and seated with Him at the Father’s right hand-and there and then welcomed, accepted, embraced forever.
The Gospel is the good news of what became of the Son of God and of what became of us in Him. It is the news that Adam and all of us were crucified with Christ, dead and buried, and on the third day Adam and all of us were quickened with new life and raised with Jesus, and then lifted up to the Father’s right hand in Jesus’ ascension and seated with Christ.
What happened on the cross? Why did Jesus die? How do we understand the meaning of His death?
The death of Jesus Christ was part of a seamless movement in which the Triune God laid hold of the human race and decisively and sovereignly altered its very existence, cleansing it of all alienation, quickening it with new life and lifting it up into union with the Father, Son, and Spirit.
It is finished.
